About your Apple ID email addresses
Learn how to add, change, or delete the different types of email addresses that you can use with your Apple ID account.
Email addresses you use with your Apple ID
Your Apple ID uses email addresses to sign you in to your account with Apple. With your Apple ID, you can access services like the App Store, Apple Music, iCloud, iMessage, FaceTime, and more. We use your email addresses to send you information about your account, and to help friends and family communicate and share with you.
This is the email address you use with your password when signing in to any Apple service. It’s also the primary email address on your account.
Add extra email addresses to your account to help people find you on Apple services like FaceTime, iMessage, and Find My Friends.
You have the option to add a rescue email address to your account for more security. You can see it when you sign in to your Apple ID account page.
Before you can use a new or updated Apple ID, we'll send you a verification email to make sure that the email address belongs to you.
Apple ID email address
When you create an Apple ID, you enter an email address. This email address is your Apple ID and the username that you use to sign in to Apple services like iTunes and iCloud. It's also the contact email address for your account. Be sure to check your email address regularly. We'll send you email notifications to help you manage your account and make the most of your Apple ID.
Follow these steps to change your Apple ID.
Additional email addresses
Many of us have more than one email address that friends and family use to reach us. Add an email address that you commonly use to your Apple ID account, so people can easily find and communicate with you on Apple services like FaceTime, iMessage, and Find My Friends.
To add an additional email address, follow these steps:
- Sign in to your Apple ID account page.
- Click Edit in the Account section.
- Under Reachable at, select Add More.
- Enter your additional email address and we'll send a verification to that address. Didn't get the email?
- Enter the verification code and click Verify.
Make sure that you enter an email address that you're not already using as an Apple ID. If you want to delete one of your additional email addresses, click 
next to the address.
Rescue email address
Having a rescue email address is optional but recommended. If you ever forget your security questions, you can use your rescue email address to reset them. We also send any account security-related notifications to your rescue email address.
